Abstract

PURPOSE:To obtain a cosmetic having excellent heat resistance, light resistance and stability to the skin, containing gold dyed protein prepared by dyeing protein with gold colloid. CONSTITUTION:Protein is added to water dispersion of gold colloid while stirring, aged for about tens minutes, filtered, washed with water and dried to give gold dyed protein. In the operation, protein is mixed with 0.1-2wt.% gold colloid. 0.01-50wt.% of the gold dyed protein is properly blended with components useful for ordinary cosmetic, such as humectant, water-soluble polymer, surfactant, water, oil, wax, perfume, colorant, antiseptic, antioxidant and germicide and prepared to give the objective substance. The substance is processed into a form such as cream, lotion, powder or spray and applicable to a wide range of cosmetic such as make-up cosmetic, hair cosmetic and face washing cosmetic.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a cosmetic with excellent heat resistance, light resistance, and skin stability, which contains a gold-dyed protein obtained by dyeing a protein prize with gold colloid. Regarding.

[Prior art and problems to be solved by the invention] Conventionally,
Cosmetics containing inorganic pigments, tar-based pigments, natural pigments, etc. are provided in order to make the cosmetics themselves look beautiful or to color the skin and hair. In addition, the required characteristics are: 1. Good color and excellent color development 2. Good stability such as heat resistance and light resistance 3. Excellent safety such as not irritating the skin 4. One of the reasons is that there are many coloring materials available and it is easy to handle manually.

However, when looking at the red color that is most commonly used as cosmetics, it has not been possible to find one that satisfies all of these requirements.

In other words, no red! Cosmetics containing pigments such as red iron, ultramarine violet, and manganese violet have low saturation and cannot provide a satisfactory color. Also cream.

When used as a coloring agent in emulsion, etc., the pigment settles.

It has the disadvantage that it easily separates and at the same time feels rough when applied to the skin.

Cosmetics containing red tar pigments have problems such as poor stability, sensitization, and carcinogenicity.

In addition, due to the recent trend towards natural products, safflower pigment, purple root pigment,
Cosmetics containing natural pigments such as carminic acid and laccaic acid have also been proposed, but these pigments are expensive and difficult to handle, and cosmetics containing these pigments do not discolor when exposed to heat or light. It had the following drawback.

Furthermore, even when attempts were made to dye these natural pigments into proteins and incorporate them into powdered cosmetics such as powder sorbs and powder foundations, dyed proteins with good color development could not be obtained.

The purpose of the present invention is to have a single color, good color development, and heat resistance.

Excellent storage stability such as light resistance, skin irritation and sensitization 1
The purpose is to provide cosmetics that are non-carcinogenic and highly safe for the skin.

(Means for Solving the Problems) The present invention is a cosmetic composition containing gold-stained protein obtained by dyeing the protein with gold colloid.

The gold colloid used in the present invention is obtained by a known method in which a gold salt aqueous solution such as chloroauric acid is used as a raw material and treated with a water-soluble reducing agent such as sodium borohydride. To stain proteins, an aqueous dispersion of colloidal gold (gold hydrosil) obtained from this keyaki is used.

In addition, the size (particle size) of gold colloid is 5 nm to 1100 nm.
is within the range of Gold colloids smaller than 5 nm are difficult to prepare industrially. On the other hand, if it is larger than 1100n, the gold colloid becomes bluish, making it impossible to obtain a bright reddish-purple gold-stained protein, which is not preferable.

The proteins used in the present invention are not particularly limited, but include, for example, collagen and its hydrolysates, gelatin and its hydrolysates, sericin and its hydrolysates, elastin and its hydrolysates, casein and its hydrolysates, keratin and its Examples include hydrolysates, albumin and its hydrolysates, enzymes, and derivatives thereof.

The gold-stained protein used in the present invention can be obtained by adding the protein to the above-mentioned gold hydrosil with stirring, stirring for several minutes, then filtering, washing with water, and drying.

The proportion of colloidal gold in the total dyed protein is preferably 0.1 to 2.0% by weight (hereinafter abbreviated as wt%) based on the protein; if it is less than 0.1wt%, the color development is weak and undesirable. Also, 2. Even if it exceeds Owt%, the color development does not change much and the color becomes dull and undesirable.

In the present invention, the blending amount of the gold-dyed protein is 0.5%, assuming the total amount of the cosmetic to be 100wt%. OI W t%~50w
t%. If it is less than 0.01 wt%, the coloring properties of the cosmetic will be insufficient, which is undesirable, and if it exceeds 50 wt%, not much effect commensurate with the blended amount can be expected.

The cosmetics of the present invention include moisturizers, water-soluble polymers, surfactants, water, oils, waxes, fragrances, colorants, preservatives, antioxidants, bactericidal agents, amino acids, vitamins, hormones, and ultraviolet rays. Ingredients commonly used in cosmetics, such as absorbents, can be blended as appropriate.

The cosmetics of the present invention include skin cream, skin luxury, cleansing cream, cleansing milk, cold cream, cream sorb 2 makeup base, skin lotion, milky lotion bag, calamine lotion, T zone essence, hand cream, and makeup base. Sense powder, whitening powder, powder soap.

Bar soap, transparent soap, T de cream 9 lipstick, nutritional essence, cream foundation essence, face powder, powder eyeshadow 5 powder foundation, nail remover, hair trick, hair liquid, hair cream, hair treatment, Applicable to scalp treatment shampoo, conditioner, hair spray, sun oil, sunscreen, shaving foam, shaving cream, baby oil, etc.

〔Example〕

The present invention will be specifically described below with reference to Examples.

In the present invention, the sensory test, light resistance test, and heat resistance test of the cosmetics were conducted as follows.

(1) Twenty inspectors specializing in sensory tests conducted the tests and responded to the questionnaire on the following items.

■ Feelings of use The number of people who answered that after applying the cosmetics, they did not feel any roughness and felt that they blended well into their skin.

■ Appearance The number of people who answered that the color taste of cosmetics was good.

■ Stimulus Number of people who said they felt irritation on their skin (scalp) after using the survey.

(2) Light resistance test Place the sample in a transparent container and expose to sunlight for 30 days.

This was compared with the same sample stored in a cool dark place, and the case where there was no change in color was rated as x and the case where there was a change in O3 was rated as x.

(3) Heat resistance test Samples were stored at 45° C. for 3 months and compared with the same sample stored in a cool, dark place. Cases where there was no change in color and cases where there was a change in O1 were marked as ×.
